Method for controlling and system for charging a battery power supply unit

摘要

A method of controlling and a system for charging a battery power supply unit for a bicycle electronic device, even in critical temperature conditions, is provided. Heat energy is supplied to the power supply unit when its temperature is lower than or equal to a lower temperature threshold within a closed charging temperature range characteristic of the power supply unit.

主权项

1. A method for controlling the charging of a rechargeable battery power supply unit for a bicycle electronic device, comprising the steps of:
providing a rechargeable battery power supply unit having a closed operating temperature range between a low operating temperature and a high operating temperature; providing a battery charging unit; providing a sensor for detecting at least one temperature of the power supply unit; defining a closed charging temperature range having predetermined low temperature and high temperature thresholds; providing a power supply unit heating element; comparing the detected temperature against the low temperature and high temperature thresholds; and activating the power supply unit heating element whenever the detected temperature is lower than or equal to the low temperature threshold.
